On this day in 1975, a confrontation occurred between union organizers and El Texano Ranch, in Hidalgo, Reynosa, Mexico. The event led to a spontaneous strike during which a ranch supervisor fired upon the strikers and their supporters. The strike lasted throughout the melon harvest and spread to the Trans-Pecos and Panhandle. Many strikers were arrested. As the strike continued, a core of Valley farmworkers supported the foundation of the Texas Farm Workers Union as a local that would be accountable to them. The TFWU was established under the leadership of Antonio Ordendain in August 1975.
